IMPROVEMENT IN COOK-STOVES.

To all whom it may concern:

Be it known that I, JOHN G. TREADWELL, of Albany, in the State of NewYork, have invented certain new and useful Improvements in Stoves; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

In the annexed drawings, making part of this specification, A representsthe body of the stove, which is made somewhat in the shape representedand in any of the known and usual ways. Upon the rear of this body aresituated the ovens B B, one above the other, as is seen.

D represents the casing around the ovens, the ovens being sufficientlysmaller than the casing to allow of a free draft between at front andback from bottom to top.

a represents a division-plate which extends from the top of the loweroven to the bottom of the upper one for the purpose of keeping separatethe front current from the back current of hot air until they reach apoint above the upper oven.

0 represents a plate situated between the two ovens and extending out onboth sides of the plate a for protecting the ventilatingopenings w 00 inthe top of the lower oven.

The doors E of the ovens are made hollow, as seen, Fig. 2, and areprovided with open ings z 2 at the bottom of the outside plate and atthe top of the inside plate for the purpose of allowing air to pass upthrough the hot doors for properly ventilating the inside of the oven.The air after passing into the ovens is allowed egress through theopenings in the top at a: 00.

Having thus fully described my invention,

direct draft is opened with the smoke-flue,

and said draft is protected, as is herein set forth. g
